SIDNEY POSEN, OF OFFENBAOH-ON-THE-MAIN, GERMANY.

- CLASP FOR ALBUMS.

SPECIFICATION formingpart of Letters Patent No. 223,756, dated January 20, 1880.

Application filed May 27, 1879.

To all whom it may concern:

Be it known that I, SIDNEY POSEN, of Offenbach-on-the-Main, Germany, have invented a new and Improved Album-Clasp, of which the following is a specification.

Figure 1 is a perspective view of the clasp in position on an album. Fig. 2 is a vertical section on line w 00, Fig. 3. Fig. 3 is a front elevation of the clasp opened. Fig. 4 is a representation, in perspective, of one of thesprin gs of the clasp.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved clasp for albums or other books that may be opened and closed and so held automatically. g

The invention consists of the metallic frame A, provided with a hole, a, just within its up- Y has its free end in contact with and pressing upward against the unsecured end of the other spring, 9, whose end piece is'set at right angles to the other part, and is provided with a terminal upward-projecting lip, h.

When the clasp is open the frame Ais held in an upright or nearly upright position by the engagement of the finger 11 against the lip h. On turning the frame down to close the clasp the finger presses down upon the end piece of the spring g and forces it back until the central point is passed, when the reaction of the two springs upon the finger snaps or throws the frame forward, so that its hole a is thrown over the pin it, that projects upward from the plate (3, that is secured on the opposite cover of the album.

On raising the frame to open the clasp the springs operate in a like manner to throw it back, but with more readiness because of the curve on the end of the finger, and the frame is prevented from being thrown back too far by the lip It, as before shown.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent 1. The within described clasp, consisting of frame A, provided with hole a" and finger 11, plate B, provided with slot 0'', springs f and g, secured within plate B, and plate 0, provided with pin k, constructed and arranged substantially as herein shown and described.

2. In the construction of an album or book clasp, the combination of frame A, provided with finger b, with plate B, provided with a slot, 0, spring f, and spring g, having a rectangular end piece that is provided with a lip,

h, substantially as herein shown and described.
